Rose Robusta (Robusta) - a description of the varietal bush

The progenitor of the Robusta rose is an old variety - Rugosa rose. This wonderful variety was bred in a German nursery in 1979, by a family of Cordesov breeders who first described a new species of roses - Robusta. Today, there are more than 20,000 different types of roses, differing in appearance, duration of flowering and growing conditions. Rosa Robusta is the most unpretentious and long-flowering variety, and that is why it is widely popular among those involved in breeding.

Rose Robusta Description and Characteristics

Rosa Robusta is a small bush whose height is only 1.5 meters and a width of 1.2 meters. What distinguishes this variety from others?

Separate Robusta bush

Among the main characteristics and features, there are several:

• This variety is characterized by saturated bright green, large leaves, which serve as a kind of frame for the variegated robust rose buds of Robusta.
• The buds are not terry, scarlet, symmetrical with a small bunch of stamens, which are difficult to notice. They are opened from elongated buds, on which short brushes appear later, releasing from 5 to 10 flowers.
• Flowering is plentiful and continuous. It starts in the middle of spring, and ends with the first frosts. Neither direct sunlight nor rains harm the buds.

Advantages and disadvantages

Rosa Robusta is not distinguished by any significant flaws that could complicate the care of the plant. At the same time, this flower has a whole list of advantages, thanks to which it gained such great fame.

Here is some of them:

• continuous flowering;
• excellent survival even in sparse soil;
• resistance to any weather conditions;
• frost resistance;
• resistance to fungal infections.

Use in landscape design

Rosa Robusta belongs to landscape gardening crops. It is convenient to use in any form of green building, including:

• creation of hedges;
• container culture;
• single landings;
• vertical gardening;
• planting in groups with roses and other plants;
• the design of borders, flower beds and rocky gardens.

Self-growing Robusta roses

In addition to the scarlet park Rose Robusta, there is also Pink Robusta, which has no significant differences. The larger buds are pink in color and the size of the shrub is slightly lower than that of the scarlet beauty. Although the differences are not significant, but for beginning gardeners, the question still arises as to whether there is a difference in the agricultural technology used when planting different shrubs of Robusta. The process of growing and planting is not significantly different.

Robusta Pink

Rosa Robusta is relatively resistant to arid climates and is not whimsical in relation to soil. But for better decorativeness, it is worth choosing a place with enough light and partial partial shade. It is necessary to pay attention to the soil agricultural background. The soil should be medium loamy. You can use such mixtures:

• humus, turf and sand - 2: 2: 1;
• sod, humus, sand and deciduous land - 1: 1: 1: 1.

As a rule, landing is made in the spring.

Agricultural technology standard:

1. A few hours before planting, Rose Robusta is placed in a solution of a root growth stimulator.
2. A pit is dug up to a depth of about 60 cm, in diameter about 70 cm.
3. A drainage layer is laid at the bottom. It can be expanded clay or other small stones.
4. The seedling is carefully placed in the pit so that all the roots look down, after which it gradually sprinkles with earth.

The last stage of planting is mulching the soil in a circle and excess watering.

Park Rose Care

In order to ensure proper care of the bushes, no complex actions are required.

Watering

Robusta needs to be watered only once every 10 days, but it is quite plentiful - about 1.5-2 buckets per adult plant. Watering is done under the root in a radius of 20-50 cm from the base of the bush. The earthball should not dry out. Approximately 5 days after watering, the earth around must be loosened for better air traffic.

Land cultivation

A trunk circle within a radius of 60 cm needs timely weed removal and weeding.

Fertilizer

Rosa Robusta responds very well to fertilizers. The main fertilizers are compost and humus. Such top dressing takes place once a year in the first half of summer, this is done by mulching with the subsequent entry into the ground during loosening.

Do not forget about liquid top dressing, which is performed 2 times a season for the first time in May and the second in August. For this, a mullein diluted in 100 liters of water and infused for 2 weeks is used. Under one bush, approximately 10 liters of this infusion are introduced.

Prevention

In order to avoid infection of the bush during high humidity, preventive spraying with fungicides is performed no more than once every 3 weeks.

Pruning

Pruning is usually done after wintering in May after the unfolding of young leaves. Everything that was damaged by frost is removed or simply dried up is cut to healthy wood. A park rose needs a rejuvenating pruning at the age of 5-9 years. For this, all trunks older than 5 years are removed under the root. You need to do this in the fall, from September to October.

Transfer

The most favorable period for transplanting Robusta roses is early spring or late autumn. Transplanting at another time entails not very pleasant consequences. But if there is an urgent need, then it will be necessary to help the plant take root in a new place.

Preparing for the winter

Despite the fact that the Robusta rose has good frost resistance, it is still worthwhile to help it cope with the cold. Although the bushes are pruned before wintering, you still can’t shorten the branches too much - this can weaken the plant, and the rose simply will not survive the winter period.

To prepare for colds over an adult bush, you can create a simple ground structure from polyethylene or any other non-fabric material. Younger plants simply bend to the ground and cover tightly with fir spruce branches.

Flowering and dormancy

Robusta begins to bloom in May, and after the first buds appear, it continuously generates new flowers. The most active flowering time occurs in mid-August - early September, and in the absence of cold weather, flowering will please the eye in October. It follows that the total flowering time lasts as long as 4-5 months.

The most important aspects in caring for a park rose during the flowering period are timely weeding and loosening of the soil. The petals of the buds do not fade, but crumble, so the rose bush will look attractive even in the process of flowering, which can not be said about the park's bushy roses.

Why the rose does not bloom

There are several reasons why a rose may not bloom:

• The first year after planting. A plant may not bloom at all. It depends on the source material used during planting. In the first year, it is better not to let Robusta blossom so that she can take root as best as possible.
• Improper care. Rose is quite demanding on living conditions, it needs additional nutrition, as well as timely treatment against pests or diseases. If the bush has already begun to drop leaves and looks painful, most likely, flowering can not be expected. However, "overfeeding", the plant is also not worth it, since excessive feeding gives enough foliage strength, and flowering becomes quite scarce.
• Incorrect pruning. It is not necessary to expose Robusta to strong pruning or try to form a "small bush" - this leads to weakening of the plant. Such actions lead to a shift in flowering time, as the rose will need to recover after such procedures.

Reproduction of Robusta's park rose

This type of rose is grown by the root method. Propagate it using green cuttings. To do this, they are cut at the beginning of lumbering, 15-20 cm long, and dipped in a solution that promotes rapid growth of the root system. After these actions, the stem with the root is planted in moistened, fertilized soil.

Park rose, pests and diseases

This type of rose is notable for its stable immunity, but sometimes you can encounter some difficulties:

• Aphid is an insect that feeds on sinewy and succulent plants. Especially often aphids attack in the summer. Most often, Karbofos or Fitoverm is used to combat this pest.
• Powdery mildew is a disease that affects the entire terrestrial part of the plant. Occurs in conditions of excessive humidity. Outwardly, it is easy enough to identify the disease, because it looks like a white-gray coating on flowers and foliage. To effectively get rid of the disease, fungicide is used.
• Rust. The bacteria that infects the leaves. Outwardly, it looks like rusty spots covered the foliage. With this bacterium fungicide perfectly copes.

Despite the fact that the park rose Robusta red is not very whimsical, it is better to follow the instructions described above during planting. Nevertheless, everyone can cope with the care of this truly beautiful garden plant. Therefore, if you have a garden or a place for a small bush, you should plant Robusta, because it is she who can perfectly decorate a cozy corner in a small yard.
